Oslo Culture Night in Oslo
Oslo Kulturnatt, or Oslo Culture Night, is Norway's largest culture festival, condensing hundreds of free events across the entire city into a single Friday each September, with the 2026 edition set for September 11. Organized by Oslo municipality's culture department, it is described locally as culture's own version of Norway's national day.
Each September, Oslo compresses what many cities would spread across a full festival week into a single Friday evening, when Oslo Kulturnatt opens the doors of museums, galleries, theaters, churches, libraries and smaller community cultural spaces across the entire city, all at once, all free of charge.
